27\times 27=x\times \frac{78}{5}
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 27x, the least common multiple of x,27.
729=x\times \frac{78}{5}
Multiply 27 and 27 to get 729.
x\times \frac{78}{5}=729
Swap sides so that all variable terms are on the left hand side.
x=729\times \frac{5}{78}
Multiply both sides by \frac{5}{78}, the reciprocal of \frac{78}{5}.
x=\frac{729\times 5}{78}
Express 729\times \frac{5}{78} as a single fraction.
x=\frac{3645}{78}
Multiply 729 and 5 to get 3645.
x=\frac{1215}{26}
Reduce the fraction \frac{3645}{78} to lowest terms by extracting and canceling out 3.
